Arrests in robbery and assault incident Two suspects in a Sevier County robbery and assault incident, were arrested Wednesday afternoon in Newport. Newport Police Captain Brad Ball said a vehicle was stopped on River Street because it matched the description of an auto wanted in connection with the robbery and severe injury of a Sevier County man. The couple allegedly assaulted and robbed Michael Mundy of Sevierville on Sunday, requiring the victim to undergo hospital treatment for his injuries. The driver of the auto, Jamie Haptonstall, 29, Kingston Pike, Knoxville, who is a native of Cocke County, and her passenger, Robert Lawhorn, 26, Stones Throw Lane, Sevierville, reportedly had been observed "shooting up" in their vehicle near the city park, prior to the traffic stop. When the auto was stopped, the driver allegedly tried to ingest pills but was forced by police to spit them out. A search of the vehicle revealed a large quantity of blood, and Oxycodone pills were found on the front and rear floorboard of the auto. In addition, Xanax pills also were found in Haptonstall's purse along with marijuana, a pill crusher, pill cutter and syringes. Both subjects are charged with especially aggravated robbery on the Sevier County warrant and Ms. Haptonstall is charged locally with simple possession or casual exchange of Oxycodone, Xanax and marijuana, possession of drug paraphernalia, tampering or fabrication of evidence and driving on a revoked license.
